What derailed Do I use on a road bike? My bike has Shimano Tiagra GS 8 spd cassette. 12-23t I would like to change to an 11-34t and drop to a 22t sprocket from a 30t crank sprocket. What derailed do I need to make this work to make work. Crank sprocket...

you can probably use the same derailer and just adjust it for the different size, as far as the chain sizes and stuff, I know almost enough to be dangerous when it comes to bike building and repairing, The way I figure it though, your current chain should be right about the correct size for the changes you are looking at making. As the other person responded make sure this will work for your hub, if you have a freehub this will work (you also need the tool to take the keeper off of the hub) if you do not, you would need a freewheel cassette. The difference is the free hub has the ratcheting mechanism in the hub and the freewheel has it in the casssette and the cassette is removed from the hub. I didn't realize there was a difference before I bought this and ended up getting a new rear wheel to go with my brand new cassette.

It all depends on your crank, this is a single speed narrow-wide chainring, no front derailuer needed. The brand of bike does not matter, the crank arm spacing and bike drivetrain are what make it compatible.

I second the comment that cassettes for 7, 8, and 9 are compatible usually on the same hub. Your derailleur and shifters will determine how many of the gears in the cassette will be used.

Howdy... all rear derailleurs need a hanger. You can buy bolt-on hangers if you don't already have one on your frame. Inespensive, but likly to break if you do a lot of rough riding. I'm not sure but I think this one will only accomodate up to about a 37 tooth chain ring. Check on Shimano's site though. My own rear cassettes only fo up to either 37 or 39 teeth.

chris, i bought a Shimano HG51 8-Speed Cassette (11-28T)--just fits my frame. it has presta size valve holes. be sure to measure your rear spacing before putting on too many gears; i believe its has the std 130mm spacing. the tires were Vittoria Zaffiro II Wire (Black, 700 x 23). great wheelset for the money!!

Dear Juice: There are two systems. One is the older-style freewheel where the cog unit goes screwed on the hub of the rear wheel. This Shimano Tourney is one of those screw-on cogs. The newer system is where the cog unit -called a cassette- goes pushed and then locked on a splined extension of the hub. Both systems are not compatible. My advise is get a bike mechanic or a friend who knows the difference between the two systems have a look at your bike and tell you which system it has before you spend the money :-) Hope this helps, Andy :-)

The main thing is, SRAM REAR derailleurs will only work with SRAM REAR shifters, and vice versa. You can never use SRAM with Shimano in the back. It doesn't matter in the front.

Yes I have a 90's Peugeot with stock black paint and orange, yellow,stripes Shimano works smoothly. If your bike came with the nylon rear derailliar it could snap in half, if hasn't allready happened, it will weaken over time , and then one day? I converted to one chain wheel on the crank, went from 12 to 6 speed, left the rear freewheel 6 cog in place, and do not have duplicated gear ratios. Removed useless shifter setup for front mess and gained functional simplicity

Measure your seat tube where the derallieur clamps on. Look at the size of largest and smallest chainrings. That is how you figure out if this will work on any bike. Or ask a bike shop to help you. Shimano clamp on style usually comes with shims for 2 or 3 tube sizes. Derallieur and shifter index must match. It can get complicated.

I currently have this on my 8-speed bike with no problems. I purchased this along with an 8-speed chain and an 8-speed cassette (chain and cassette were made by SRAM). I'm very satisfied with it.

Yes you need a rear derailleur hanger. Yes this will work with a 44T front crank chainring, the shimano crank set I paired this with was a 22, 32 44T, however I ended up taking the 44 off and replacing it with a bash guard. The largest you can go on the cassette is 36T.

Unfortunately they don't put barrel adjusters on deraileurs anymore. SRAM started it and Shimano followed. You need an inline adjuster now...

11-36, 12-36 gearing is typically for mountain or cross bikes. If this is going on a road bike, most likely your derailleur is too short and will not work with the the larger gears. Most road cassettes only go up to 28t (and that is probably the max a "short-cage" derailleur can take). If you want easier gearing, go with 12-28t, compact chainrings in the front, or get a med-cage derailleur to handle the 12-36.

Honestly I wouldn't spend a penny on this. Had its week and it broke on me. No hard riding either only just casual. If ur looking for a good derailleur, I'd start at shimano 105. My road bike has 105 competes and I have not had a problem at all

I can't completely answer your question. I have a Tiagra derailleur and I must say it took some time to adjust so that the 28 didn't hit the derailleur. But after some adjusting, I'm very happy with the performance.

This will work, but you need to check on the shimano web site to see if your rear deraileur will work with the 28 tooth cog. Mine made noise because the idler gears were making contact with the 28t cog. I ended up buying a new mid length cage rear deraileur. They are pretty cheap online.
